This　study　examineshowandwhenentrepreneurial　orientation　(EO)　enhances　alliance　performance　by　considering　knowledge　integration　as　a　critical　mediator　and　bonding　as　an　important　contingency　of　the　mediation　effect.　We　test　this　moderated　mediation　framework　using　a　sample　of　410　alliance　firms　(based　on　a　total　of　820　respondents).　Our　results　show　that　knowledge　integration　fully　mediates　the　relationship　between　EO　and　alliance　performance　and　that　this　indirect　effect　is　stronger　at　a　high　level　of　bonding.　Overall,　we　contribute　to　the　entrepreneurship　literature　by　revealing　how　firms　translate　their　EO-based　strategies　into　positive　alliance　outcomes　through　knowledge　integration　and　when　this　indirect　effect　is　most　effective.
